T all whom it 727 (43 concern Be it known that l, Eowano .l. Bnosxax. acitizen of the Ynited States. residing at Troy. in the county ofRensselaer. State of New York. have invented certain new and usefulImprovements in Bottle-Stoppers and Droppers: and I do hereby declarethe following to be a full. clear. and exact description of theinvention. such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to bottle closures. and is directed moreparticularly to a dropping stopper of improved and novel construction.

3m object of the present invention resides in the provision of a bottleclosure embodying novel means by which a quantity of liquid may bewithdrawn from the bottle and discharged drop by drop.

A further object of the invention is to provic e a bottle closure of theabove nature in connection with whicl a collapsible bulb may be employedfor drawing the liquid into the dropping tube and manipulated todischarge the same.

With the above and other objectsof similar nature in view the inventionconsists in the construction. combination and arrangement of parts setforth in and falling within the scope of the appended claim.

In the drawing :Figure 1 is a side elevation of theimproved closureapplied to a bottle: Fig. 2 is a vertical sectional view therethrough:Fig. is a top plan view with the plug and bulb removed, and Fig. l is afragmental sectional view with the plug and bulb removed and a closuresubstituted therefor.

Referring now more particularly to the drawing. theinvention isdesignated generally at A and is illustrated as associated with the neckB of a bottle of conventional type.

Specifically the closure A comprises a stopper 5 preferably of glassground to fit snugly in the bottle neck B. The stopper 5 is providedwith a central passage 6 extending longitudinally therethrough from endto end and carried by the stopper is a dropping tube 7 adapted when notin use to eX- tend within the bottle. lhis tube is preferably blown orotherwise formed in conjunction with the stopper 5 and is arranged tocommunicate with one end of the passage 6.

Zemovably engaged in the other, end of the passage 6 and fitted snuglythel'ein a plug 8 the upper end of which extends a shortdistance beyondthe stopper and has engaged thereon a collapsible bulb 9 similar tothose found in medicine dropper-s or the like. Communication between thedropping tube T and bulb 9 is established bv providing in the plug 8 anaperture ll Thus when the bulb is collapsed and then released. a portionof the contents of the bottle will be withdrawn into the tube T and maybe discharged therefrom drop by drop or otherwise by compressing thebulb. it being of courst inderstood that the device has in the meantimebeen removed from the bottle neck.

If the bulb should at any time become nuserviceable or should it not bedesirable to employ the same inconnection with a bottle containing aliquid which might have a detrimental effect upon the rubber from whichit is formed. the same may be entirel dispensed with by removing'theplug 9 from the stopper. and a closure such as shown at ll in Fig.substituted to prevent evaporation of the bottles contents. However evenshould the bulb 9 be dispensed with. the device may still be employed asa dropper by merely removing the closure 11; and. with the fingerclosing the entrance to the passage (5. withdrawing the stopper from thebottle neck. it is of course understood that by excluding the air fromthe passage (3. the liquid contained in the tube will remain thereinuntil air is admitted to displace the liquid. This is effected by merelyrelieving the pressure upon the finger posi tioned over the passage 6.the air entering said passage and forcing the liquid outwardly throughthe tube 7 either drop by drop or otherwise as desired.

To assist in producing an even or con stant inflow of air into thepassage (3. the stopper 5 is provided in its top face with a transversegroove 1'2 the inner end of which communicates with the passage. Thuswhen pressure upon the finger is relieved a constant supply of air wi lbe admitted through said-groove to the passage, thereby permitting thedischarge of liquid from the tube to be more readily controlled.

What is claimed is The combination with a bottle-stopper having a.passage therethrough. and a dropping tube forming a continuation of thestopper-and connnuuicnting with one end of the passage, of an aperturedplug inserted in the other end of the passage, and a collapsi: blebulb'carried by the pl ug. said plug and bulb being removable from thepassage for the substitution of a closure therefor.
